Vhen the discharging operation is over, -the carrier with Wagon, under the control of the loaded holding chains or equivalent and the rotating means is rotated in the opposite direction until it assumes a position from which it will return to its original position by gravity. During the latter movement, the inner side of the tiltable platform will, through the rollers carried thereby, or equivalent means, come into contact with the stationary abutment means which will act gradually to return the tiltable platform to the normally horizontal position when the carrier reaches its normal position. The -platform then rests on the said abutment means and on the stationary support at the opposite side of the platform.

The lateral support whilst not arranged to be moved bodily towards the wagon, may be mounted to tilt sideways to a limited extent, it may be against the action of a spring or springs, to enable it automatically to bear in an effective manner against the adjacent side of the tilted wagon. For this purpose, it may be mounted in the carrier in such manner that it can turn about a horizontal axis. It may also be arranged to be positively operated through suitable connecting means from lugs or brackets on the inner side portion of the rocking platform.

In the accompanying illustrative drawings, Fig. l shows in side elevation, a portion of wagon tipping apparatus of the kind herein referred to, the carrier of which is provided with a rocking platform according to the invention. Fig. 2 shows the platform `and part of the carrier 1n horizontal section taken on the line Il-II of Fig. l, whilst Fig. 3 shows the platform aloneI in end elevation. Fig. 4 shows a portion of the carri-er and platform in longitudinal section whilst Fig. 5 shows such portion in plan. Fig. 6 an end elevation and Fig. 7 a side elevation, showing, to a larger scale than Figs. l to 5, one construction of late-ral support and means for positively tilting such support about a. horizontal aXis. Fig. 8 shows in end view, a carrier with rocking platform and self adjustable lateral support. Fig. 9 shows in end elevation, wagon tipping apparatus with a modified arrangement of carrier with rocking platform and self adjustable lateral support. Fig. l() is a detail view.

Referring to Figs. l to 5, a is a carrier adapted to be tilted about a stationary horizontal axis by hoisting and lowering ropes b and hoisting and lowering drums, in a well known manner. e is the portion of the carrier provided with rails f on to which a wagon to be tipped is run and which, according to the invention, is, as hereinbefore stated, constructed as a movable or rocking platform. Forthis purpose, the platform, consisting' of a structure comprising connected longitudinal and transverse members @l and @2 respectively, suitably braced together by diagonal members e3, is provided at its ends with trunnions g journalled in bearings in the end members of the carrier a.. The longitudinal axis of the trunnions g is located, as hereinbefore described, so that the inner side portion of the platform, namely that portion at the right hand side of Figs. l, 2 and 3, would tend to tilt downward, if free. Below this side portion of the platform is a stationary abutment L, constituted, in the example, by a concrete block or blocks, against which the inner side portion normally bears through the intervention of rollers z' mounted in brackets il on the unuerside of the platform, so as then to hold the platform horizontal with the rails f thereon in alignment with. the rails on the adjacent permancnttracks. Stationary.supporting means for the opposite or outer' side of the platform are provided, constituted by another concrete block or blocks 7c.-

m is a longitudinal lateral support provided at its ends with trunnions at n journalled in the end members of the carrier a and against which a wagon on the rocking platform will bear sideways when the carrier is lifted by the ropes Z) from the abutment 7L. rIhe lateral support m in this example is arranged to bepositively turned about the common axis of its trunnions a when the inner side portion of the platform is allowed to tilt downward. ln the arrangement now being described, the lateral support consists, as shown more clearly in Figs. 6 and 7, of a built-up structure comprising two double channel or section bars m1, m2 arranged horizontally one above the other and connected together at the inner side thereof byupper and low-er longitudinal packing strips or members m3, m4 to which are secured, atintervals, vertical members m5 whilst to the opposite or outer side of the bars m1, m2 are connected other vertical members m6 and vertical bracket plates m7. The longitudinal and vertical members m3, m4, m5 at the inner side of the double channel bars may, as shown, be of wood and to the vertical members m5, hemp rope 0, rubber belting or the like may be applied on the side that will be next a wagon'on theV carrier, to serve as a fender or cushioning means for the wagon to rest against when tilted.

The built-up lateral support thus constructed is suitably mounted, as by the end trunnions at n, to turn about a horizontal axis 1n the carrier a. To each bracket plate m7, of which there may be two arranged as described andshown,

The link t, may, as shown, be built up of parallel metal4 bars with interposed distance pieces t1, rllhe arrangement is suclr that when the inner side of the rocking platform el tiltsvdownward, the lateral support m Will` be tilted in the carrier a in av positive `mannerby the; link andlever mechanism to bring its supporting surface more-or less .parallel to the adjacent side of the tilting Wagon on the platform,

VJche parts being positively .returned to their original position when the rocking platform is afterwards caused to resume itshorizontal position by the stationary abutment means 7a.
